You really should read the fine module docs (namely, http://docs.python.org/library/codecs.html ). codecs.getwriter() returns a StreamWriter subclass (basically). The constructor of said subclass has the signature: StreamWriter(stream[, errors]) You want the 'errors' argument. So all you have to do is add one argument to your stdout reassignment: sys.stdout = codecs.getwriter(encoding)(sys.stdout, 'replace') Yay Python, for making such things easy!
